The objects in the video supervisory systems, such as underwater detecting, industrial endoscope or pipeline detecting, due to the large noise and low contrast and scattering of light, we cannot directly use the classical threshold method to segment these images which are in non-uniform illumination conditions. In order to solve the problem, this paper proposed an annulus dividing threshold method based on the classical threshold method. The experiment demonstrated the proposed algorithm outperforms the other traditional methods.
